I would wait for Caddy 2 at this point, for I found 1.0 doesn't work very well when your site gets complicated - many directives conflict with each other. Fortunately it seems that most of these are solved in 2.0.

Don't wait, start using it now while we're in beta so we can fix problems before they affect everyone!

And even bring your config with you: https://github.com/caddyserver/nginx-adapter
